Polysiloxane, di-Me, Me Wasserstoff

Beschreibung:

Polysiloxane, di-Me, Me Wasserstoff, allgemein bekannt als Dimethylhydrogensiloxan, ist eine Art von Silikonpolymer, das durch sein einzigartiges Siloxan-Rückgrat gekennzeichnet ist, das aus abwechselnden Silizium- und Sauerstoffatomen besteht. Diese Verbindung weist typischerweise Dimethylgruppen (–Si(CH3)2) und Wasserstoffatome auf, die an Silizium gebunden sind, was zu ihrer Vielseitigkeit in verschiedenen Anwendungen beiträgt. Die Anwesenheit von Wasserstoff in der Struktur ermöglicht Vernetzungsreaktionen, was sie nützlich bei der Formulierung von Silikonelastomeren und Dichtstoffen macht. Polysiloxane zeigen eine hervorragende thermische Stabilität, chemische Beständigkeit und eine niedrige Oberflächenspannung, was ihre Leistung in Beschichtungen, Klebstoffen und Körperpflegeprodukten verbessert. Darüber hinaus sind sie bekannt für ihre geringe Toxizität und Biokompatibilität, was sie für medizinische Anwendungen geeignet macht. Die Eigenschaften des Materials können durch Anpassung des Molekulargewichts und des Verhältnisses von Dimethyl- zu Wasserstoffgruppen angepasst werden, was eine breite Palette von physikalischen Eigenschaften und Funktionalitäten ermöglicht. Insgesamt werden Polysiloxane für ihre Flexibilität, Haltbarkeit und Widerstandsfähigkeit gegenüber Umwelteinflüssen geschätzt.

Siloxane-Based Silane Reducing Agent
Organosilanes are hydrocarbon-like and possess the ability to serve as both ionic and free-radical reducing agents. These reagents and their reaction by-products are safer and more easily handled and disposed than many other reducing agents. The metallic nature of silicon and its low electronegativity relative to hydrogen lead to polarization of the Si-H bond yielding a hydridic hydrogen and a milder reducing agent compared to aluminum-, boron-, and other metal-based hydrides. A summary of some key silane reductions are presented in Table 1 of the Silicon-Based Reducing Agents brochure.
